Vesting is not a standalone legal concept under Brazilian law — but it can be implemented and enforced through a shareholders’ agreement (“acordo de sócios”), with practical effects equivalent to those in any jurisdiction that has a specific legal regime for it.
Startups that ignore this often find out the hard way: a co-founder leaves early and walks away with a slice of the cap table disproportionate to their contribution. This article explains how vesting works in Brazil, how to structure it legally, and what to watch out for in terms of taxation and founder departures.
TL;DR
- Vesting in Brazil is implemented through a shareholders’ agreement (“acordo de sócios”) — there is no specific statutory regime for it.
- The cliff is the minimum period before any equity vests; without it, any early departure dilutes the cap table.
- Single trigger acceleration and double trigger acceleration define what happens to vesting upon liquidity events.
- “Bad leaver” and “good leaver” provisions determine the price at which a departing founder sells their equity.
- Taxation depends on the structure: equity granted at formation, equity purchased over time, and stock options each have different tax treatments.
- Vesting doesn’t eliminate the risk of a founder leaving — it defines the cost of that departure for both sides.

1. The Co-Founder Who Left Early
Two founders set up a healthtech startup in 2022, each holding 50% of the equity (“cotas,” the ownership units in a Brazilian limited liability company). Their shareholders’ agreement was simple — it covered only preemption rights and tag-along rights. There was no vesting clause at all.
By month 14, one of the founders left for another opportunity. Under the existing structure, he kept his 50% stake. When the startup went to market to raise a seed round, investors spotted the problem immediately: half the company belonged to someone no longer working on the business. The round was delayed by six months while the cap table was renegotiated. The departing founder eventually agreed to return part of his equity in exchange for compensation that had never been set out in any contract.
The cost — in money, time, and strained relationships — could have been avoided with a vesting clause in the original shareholders’ agreement.
2. What Vesting Is — and Why Brazilian Law Has No Specific Regime for It
Vesting is a mechanism by which a shareholder or employee gradually earns full rights over equity or ownership interests, over time or upon meeting certain conditions. Until a portion has “vested,” it remains subject to transfer restrictions or can be clawed back by the company or the other shareholders.
Brazil has no specific statute governing equity vesting for founders. What does exist:
- The Civil Code (Law 10.406/2002) allows a shareholders’ agreement to impose restrictions on the transfer of equity and conditions on the exercise of corporate rights.
- Law 6.404/1976 (the Brazilian Corporations Law) provides mechanisms for S.A.s (corporations), including share classes with transfer restrictions — more commonly used in stock option plans at larger companies.
- Law 13.874/2019 (the Economic Freedom Law) reinforced contractual freedom between parties, including in corporate agreements, which expands the room for more sophisticated vesting structures within shareholders’ agreements.
For most startups incorporated as a Sociedade Limitada (“Ltda.,” Brazil’s equivalent of a limited liability company), vesting is implemented exclusively through the shareholders’ agreement — and how well the mechanism works depends entirely on how well that agreement is drafted.
3. Legal Structure: How to Implement It in the Shareholders’ Agreement
Implementing vesting in a Ltda. generally follows one of two models:
Model 1 — Equity Subject to Buyback (Reverse Vesting)
The founder receives all of their equity at the company’s formation, but the shareholders’ agreement grants the company (or the other shareholders) the right to repurchase any unvested equity in the event of early departure, at the original issue price or at par value. This buyback right diminishes over time (or as conditions are met).
This is the simplest model to implement in an already-formed Ltda.
Model 2 — Deferred Equity Transfer
Equity corresponding to future ownership is issued in installments, according to the vesting schedule. The founder only becomes the owner of each installment once the corresponding period is complete. This model is cleaner from a cap table perspective, but requires a governance process for each issuance (an amendment to the articles of association or registration of the issuance).
Essential Elements of the Shareholders’ Agreement:
| Element | What to Define |
|---|---|
| Total ownership stake | The final percentage the founder will hold once vesting is complete |
| Total term | The overall length of the vesting schedule (e.g., 4 years) |
| Cliff | The period during which no equity vests (e.g., 12 months) |
| Vesting cadence | How often equity vests after the cliff (monthly, quarterly, annually) |
| Acceleration triggers | Events that speed up vesting (company sale, termination without cause) |
| Buyback price | The amount paid for unvested equity upon departure (bad leaver vs. good leaver) |
| Definition of departure | What qualifies as a good leaver vs. a bad leaver scenario |
The shareholders’ agreement must be filed with the Board of Trade (“Junta Comercial,” Brazil’s state-level business registry — Civil Code, art. 997, and Normative Instruction DREI No. 81/2020, issued by the Department of Business Registration and Integration) to be enforceable against third parties, including new shareholders and investors.
4. Cliff, Acceleration, and Liquidity Events
Cliff
The cliff is the initial vesting period during which the founder earns no equity at all. Only at the end of the cliff does the first installment vest. The market standard for startups is a 12-month cliff.
Example: a 4-year vesting schedule with a 1-year cliff.
- Months 1 through 12: no equity vests.
- Month 12: 25% of the total stake vests all at once.
- Months 13 through 48: 1/36 of the remaining stake vests each month.
The cliff protects the other shareholders and investors from a very early departure that would leave a founder with a significant stake despite having barely contributed to the business.
Single Trigger Acceleration
Single trigger acceleration occurs when a single event — typically the sale of the company or another liquidity event — accelerates the founder’s vesting, in full or in part. The founder immediately vests in 100% (or a defined percentage) of the previously unvested equity.
Risk for investors: single trigger acceleration can reduce a buyer’s interest in the deal, since founders become “wealthy” upon signing and may leave shortly after closing, with no minimum retention period.
Double Trigger Acceleration
Double trigger acceleration requires two simultaneous events: (a) the sale of the company; and (b) the founder’s termination without cause by the acquirer within a defined period (e.g., 12 months after closing). Vesting only accelerates if both events occur.
This model better balances the interests involved: the founder isn’t indefinitely tied to the acquirer, but also doesn’t walk away with everything at signing without any commitment to the transition.
Relevant Liquidity Events
The shareholders’ agreement should define what qualifies as a liquidity event for acceleration purposes:
- Sale of a controlling stake (change of control)
- Merger or consolidation
- IPO (Initial Public Offering)
- Sale of substantially all of the company’s assets
Leaving this vague invites disputes. A capital investment that doesn’t involve a change of control rarely qualifies as a liquidity event — but if the agreement doesn’t say so explicitly, the argument is there to be made.
5. Founder Departure: Good Leaver, Bad Leaver, and What Happens to the Equity
The distinction between a “good leaver” and a “bad leaver” is at the heart of the departure mechanism in vesting.
Good leaver: the founder leaves for reasons beyond their control or without fault — serious illness, disability, death, or termination without cause by the other shareholders. Under good leaver provisions, the founder typically has the right to receive fair value (market value or book value) for equity that had already vested, and returns the unvested portion at issue price or par value.
Bad leaver: the founder leaves on their own initiative without justification, or in breach of contractual obligations — voluntary resignation, competing with the company, breach of an NDA, or termination for cause. The buyback price for vested equity in this scenario tends to be less favorable (par value, issue price, or even zero for the unvested portion). Some structures provide that, in a bad leaver scenario, unvested equity is simply cancelled without payment.
What the shareholders’ agreement should clearly define:
- A precise definition of “good leaver” and “bad leaver” — non-exhaustive lists leave room for disputes.
- The buyback price under each scenario (issue price, book value, market value with or without a discount).
- The deadline for exercising the buyback right after departure (e.g., 90 days).
- A valuation mechanism for market value, if that’s the chosen criterion (an appraisal, a revenue multiple, or agreement between the parties).
- What happens if the remaining shareholders don’t exercise their buyback right — can the departing founder sell to a third party?
6. Taxation: What Changes Depending on the Structure
There is no specific tax regime for vesting in Brazil — what exists are general rules applied to each structure. The most common scenarios:
Equity Received at Formation (Reverse Vesting)
When a founder receives all of their equity at incorporation at the issue price (usually par value), there is no taxable event at that point. Capital gains tax applies only when the equity is sold. The personal income tax rate on capital gains ranges from 15% to 22.5%, depending on the size of the gain (Law 13.259/2016).
Equity Purchased by the Founder Over Time
If the founder acquires the equity in installments at market value, each acquisition is treated as a purchase — no tax due at that point, but it establishes a cost basis for future capital gains purposes.
Stock Options (“Plano de Opção de Compra de Ações”)
For S.A.s (corporations), stock option plans are governed by Law 6.404/1976 (art. 168, §3). For Ltdas., there’s no specific statutory provision, but similar plans can be structured contractually. Whether the benefit is treated as a commercial transaction (not taxed as salary at the time of grant) or as compensation (treated like salary, subject to social security contributions and withholding income tax) is a matter still debated in the case law of the Superior Court of Justice (“Superior Tribunal de Justiça,” Brazil’s highest court for non-constitutional matters, “STJ”) and the Superior Labor Court (“Tribunal Superior do Trabalho,” “TST”). The prevailing view at the STJ is that stock options of a commercial nature are not salary — but this needs to be assessed case by case, looking at whether the plan involves payment, is voluntary, and carries genuine risk for the recipient.
Watch out for: Complementary Bill 1.087/2024, currently under discussion in the Brazilian Congress, proposes a specific tax regime for stock options. Check whether it has been enacted before structuring any plan based on current law.
7. Frequently Asked Questions
Is vesting mandatory for startups planning to raise investment?
It’s not legally mandatory, but it’s expected by virtually every venture capital fund and accelerator during due diligence. Investors want assurance that founders will stay committed to the company through the growth period the capital is meant to fund. A cap table with founders who have no vesting is seen as a governance red flag — and can stall or make a funding round more expensive. Market practice is a 4-year vesting schedule with a 12-month cliff for founders, which can be adapted for key employees. Even companies with no immediate plans to raise capital benefit from vesting as internal protection among shareholders: it sets the cost of an early departure before that scenario actually happens, when negotiating it is much easier.

Can vesting be added to a company that’s already formed, with an existing shareholders’ agreement?
Yes, but it requires all shareholders to agree to amend the shareholders’ agreement. Since a vesting mechanism changes each shareholder’s property and exit rights, it’s a material amendment that typically requires unanimous consent or a qualified quorum, depending on the current articles of association. The process involves: (a) negotiating and drafting the new agreement or amendment; (b) signature by all shareholders; (c) filing with the Board of Trade. This is also a good moment to assess whether the current cap table reflects each shareholder’s actual contribution — and, if it doesn’t, whether there’s an interest in adjusting it before implementing vesting. Leaving that alignment unaddressed tends to create problems down the road.

What’s the difference between equity vesting and an ESOP (Employee Stock Option Plan)?
Equity vesting (or reverse vesting) is the mechanism by which a shareholder — usually a founder — gradually earns full rights over equity that has already been issued in their name. An ESOP is a program under which employees — who are not shareholders — are granted the right to acquire an ownership stake in the future, upon payment of a defined exercise price, generally after a vesting period that includes a cliff. Both mechanisms coexist at more mature startups: founders have vesting over their original equity; employees hold options under an ESOP, drawn from a portion of the cap table set aside for that purpose (the equity pool). The tax treatment and legal structure of each mechanism differ — an ESOP requires a formal plan approved by the shareholders and typically reserves between 10% and 15% of the cap table for the option pool.
